windows activation keeps popping up

Hi,
I am new to forum and not very good at computer, so I am asking for help from the experts.
Windows Activation message keeps popping up and I saw a thread from back in 2014, but not sure what to do. I hope I did the report right!

______________________________

Can you simply explain what I need to reset to fix this? I have called in the automatic phone reactivation system several times and then a few days later, the message reappears.
Thanks for the help!
K. Kleissle

where did you get the OS? was it pre installed or bought seperately?

Here is the problem I see.
How did you come by this operating system and license.

From the posted log.

License Status: Additional grace period (KMS license expired or hardware out of tolerance)
Time remaining: 4260 minute(s) (2 day(s))

Very good read.

Understanding Windows KMS and MAK volume license activation

if you have a product key try rre-entering it.

the liscence type is COA, yet the product id indicates an OEM liscence

As you have had a lot of problems & Dell have replaced the motherboard & other items it's possible they will should have given you a new Activation Code as the original one is locked to the original motherboard which no longer exists.
Keep hounding Dell.

This type of problem is actually fairly common - and the error message is a little misleading. The important part is the second one...

or hardware out of tolerance

In most cases this is due to a change in the MAC address of the NIC (for those techies watching the thread) but I think in your case it could be related to your graphics problems - so we need to work out why this is happening.

Please post a Speccy report - Speccy - System Information - Free Download -
please also follow the Windows Update Posting Instructions and post the requested data

If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

Please also post the C:\Windows\windowsudpate.log file
